✦ Synopsis

We have investigated the evolution of the field quantum entropy and the entanglement of the atom-field in the Jaynes--Cummings model without the rotating-wave approximation, and examined the effects of the virtual-photon processes (the counter-rotating terms) on the evolution of the field quantum entropy and the entanglement of the atom-field. Our results show that under the condition of the initial strong field, the virtual-photon processes play an important role for the evolution of the field quantum entropy and the entanglement between the atom and the field.

In the frame of the time-convolufionless generalized master equation approach, an analysis of a spin relaxation is made within and without the rotating wave approximation. The non-Markovian reduced dynamics is investigated, giving explicit expressions for the time-dependent involved coefficients, an
